1. A display module, comprising: a display area and a non-display area located on a side of the display area, wherein the non-display area comprises:
a support portion;
a flexible display panel located on the support portion and comprising a bent portion, wherein the flexible display panel further comprises a first flat portion and a second flat portion, the first flat portion is connected to a first end of the bent portion, the second flat portion is connected to a second end of the bent portion, and the first flat portion is disposed in parallel with the second flat portion;
a flexible cover plate layer located on the flexible display panel;
a first flexible filling portion located between the bent portion and the flexible cover plate layer;
a polarizing layer located on the flexible display panel;
an optical clear resin (OCR) layer located on the polarizing layer, wherein the polarizing layer and the OCR layer are located between the flexible display panel and the flexible cover plate layer, the first flexible filling portion and the OCR layer are disposed in a same layer and have an equal thickness, and the thickness of the OCR layer is greater than thicknesses of the flexible display panel and the polarizing layer, wherein in an extending direction from the display area to the non-display area, an orthographic projection of an end portion of the first flexible filling portion on the flexible cover plate layer is located in the flexible cover plate layer; and
an ultraviolet curing adhesive layer located on the bent portion, wherein a first side face of the first flexible filling portion is connected to the ultraviolet curing adhesive layer, and a second side face of the first flexible filling portion is connected to the flexible cover plate layer, wherein the ultraviolet curing adhesive layer and the polarizing layer are disposed in a same layer, and a thickness of the ultraviolet curing adhesive layer is greater than the thickness of the polarizing layer, wherein a junction of the ultraviolet curing adhesive layer and the polarizing layer is between a junction of the first flexible filling portion and the OCR and the bent portion;
wherein the support portion comprises a first back panel layer, an elastic support layer, a rigid support layer, a reinforced support layer, and a second back panel layer disposed in sequence, the first back panel layer is attached to the first flat portion, and the second back panel layer is attached to the second flat portion.
